Question

I'm doing my science homework and I have a hard question I cant answer. The question is:
how do we look like when we pay attention?
I would really apperciate if someone would help me with this.
Thank You!

When you pay attention, your eyes are on the speaker and you show some physical response to him/her. You may also be taking notes and asking questions.

So is it kinda like a camera?
